There are so many one to many relationships with client assets. One example being vendor contacts which would be useful to set as a global asset with the same customization with the current asset design in place. The difference being the asset can be selected to appears for the clients of our choosing and when updating the asset, it updates the the asset for all other clients its linked too.
An example would be have an asset called Vendors. Inside that Vendors asset have one called Dell and fill out the custom fields for this asset. Then be able to assign that asset to Client A,B,D, and F but not C and E. Then whenever Dell changes their contact phone number or any other information we customize, we update it in a single source of truth that updates for all clients who have that asset linked.
